According to a history of Lancaster County, Pa., "Lewis Walker, one of the descendants, became a follower of George Fox, who was at this period establishing the Quaker or Friends Society, and thereby was disowned by his kinsmen and ancestry, and in every manner separated from them in social, secular, and religious interests, and deprived of all government honors heretofore inherited or possessed; or, in the language of a follower of George Fox, ‘he laid down these honors conferred by government.' He left his mother-country about 1684, settling at or near Valley Forge, Chester Co., purchasing from William Penn (his particular friend and companion and co-worker in establishing the doctrines of the Society of Friends or Quakers) one thousand acres of land, continuing to pursue his original occupation, that of husbandry, in a style much like his ancestors of England."

This is about one of his descendants: "William Thomas, the father of Sarah (Thomas) Anderson [. . .] was the second child and eldest son of Reese and Priscilla (Jarman) Thomas, and was born in the old Thomas "Mansion House" erected by his father, July 8, 1762, and lived there all his life. He married, April 5, 1768, Naomi Walker, born February 17, 1765, died May 4, 1817, daughter of Joseph and Sarah (Thomas) Walker, granddaughter of Isaac and Sarah (Jarman) Walker, and great-granddaughter of Lewis Walker, who had come from Merionethshire, Wales, in 1687, [. . .] removed to Tredyffrin township, Chester county [. . .] Here Lewis Walker died in the winter of 1728-9, his will dated December 14, 1728, being proven January 24, 1728-9. He had married at Haverford Meeting, April 27, 1693, Mary Morris, a native of Wales, who is said to have crossed the ocean in the same ship with him. She died in 1747." [5, 6]
